1o claims. (c1. 93-63) This invention relates to new and useful improvements in machines for forming cut-outs in a continuous web passing through said machine, and for subsequently securing to said web in positions overlying said cut-outs, transparent or 4other sheet material in shapes and sizes corresponding more or less r:losely to cutout apertures themselves.

A principal object of the invention is to prol0 vide a machine of the character set forth having novel means for forming an opening in a web.

A more specific object of the invention is to providej a machine of the type described having novel'means for displacing the portion cut from the web, out of the plane of ltravel thereof.

Another object of the invention is to provide a machineof the stated character having-'novel means for removing the portion eut from the web from the machine.

Another object of the invention is to provide a machine as set forthhaving novel means for applying adhesive substances to the web adjacent the aperture cut therein.

Another object of the invention is to provide mechanism for accurately positioning and securing a covering of transparent material over Y the aperture formed in the web.

Another object of the invention is to provide a4 machine of the stated character having novel means for severing predetermined lengths of a transparent web for the purpose of covering the opening formed in a second web.

A further object of the invention'is to provide a machine as set forth having a novel mechanism effecting the accurately timed occurrence of thevarious successive operations performed in the machine.

Other detail features and objects will be set 40 forth hereinafter and are disclosed in the accompanying drawings, in which Figure 1 is a view in side elevation of the machine constituting my invention;

Figure 2 is a view in plan view of the disclosure in Figure 1;

Figure 3 is a view in vertical section through the machine showing in addition the complete cam mechanism;

Figure 4 is a view in section on line 4 4 'Figure 3; and

Figure 5 is a view on line 5 5 Figure 2.

Referring now more particularly to the drawings, a machine made in accordance with my invention comprises the vertical side supports l and 2 suitably spaced by the transverse bars 3.

a machine as set forth having a novel feed In the present instance the continuous webv 4 of paper, or like material, is carried longitudinally through the machine by the carrier rolls 5, 6 and 7 rigidly mounted respectively upon shafts 8, 9 and 10 which are rotatably journaled in 30 the side supports 1 and 2. The shaft 8 in the present instance extends outwardly beyond the side supports 1 and 2 and is provided with the gears 1ll and 12 rigidly mounted at the extremities thereof. In a similar manner the shafts 9 and 10 are provided with gears 13 and. 14 mounted respectively at the'extremities thereof adjacent the outer face of the side support' 2. Rotation of the shaft 8 is effected preferably by means of a chain or belt 15 driven 70 by a sprocket wheel 16 arranged for rotation with the main shaft 17 of the machine and to which a source of rotative'power is applied through the larger sprocket gear 18. A The chain passes from the Wheel 16 about a similar Wheel 75 19 rigidly mounted upon a transverse stub shaft 20 rotatably journaled in the side support 1. A gear 21 is mounted on the shaft 20 adjacent the wheel '19, and arranged for rotation therewith. The gear 21 is meshedwith a similar 80- gear 22 rigidly mounted on a shaft 23 rotatably mounted in bearings in the aforementioned side supports 1 and 2 respectively. 'I'he aforesaid gear .11 in meshing with the gear 22 completes the driving connection between the shaft 8 85 and the drive or main shaft-17 effecting rotation of the said shaft 8. Rotation of the shaft 9 is effected by the gear 12 at the opposite end of the shaft 8 which meshes with an idler gear 24 in turn meshing with the gear 13 on the said 90 shaft 9. The spindle 25 on which the idler gear 24 is mounted is provided, in the present instance, with a sprocket wheel 26 having a chain 27 thereabout -subsequently passing aboutl a wheel 28 rigidly mounted on the shaft .-10 hav` 95 ing the web carrier roll 7 mounted thereon. Tension on the chain 27 is, in*` the present instance, adjusted by selectively positioning the small sprocket wheel 29 rctatably .mounted on the outwardly extending stub shaft 30. It should be noted that the gears and spindles imparting, rotation to the web carrier rolls 5, 6 and 7 respectively as described above are of the same diameter andY effect proper timing for the advancement of the web 4 through the 105 machine. l

A gear 31 of substantially the same diameter as the gears 'mentioned above is meshed with the gear 11 andrgidly mounted on a shaft 32 rotatably journaled the supports 1 and 2. 110

Suitably positloned'upon Athe shaft 32 are the lcylindrical segmental cutter' supports 33, 33

respectively supporting in each instance a segmental cutter 34 disposed parallel withrespect to the longitudinal axis of the machine and arranged for cutting contact. with the web 4- against the peripheral surface'of the carrier roll 5, the said cutters 34 eachl effecting a longitudinal cut in theweb 4. A longitudinally Vpositioned rectangular 1 or other suitably shaped segmental cutting edge 35 Ais mounted upon a 'segmental section 36 removably mountedon the shaft 23, the rotation of the said shaft 23 being suitably timed and the cutter 35 being Aso positioned that as the web 4 advances through the machine the said cutter 35 will further contact with the web against .the roll 5 coinciding with the previous cuts produced by the cutters 34 as described supra, comshaft 23.

For the purpose 'from the web 4 outwardly of the machine, I

pleting the cutting of a blank from the center of the web.

For the purpose of displacing the blank from the web 4 and leaving an aperture 37 therein,

-I provide a plunger- 38 extending diametrically through the shaft 23 as shown in Fig. 3 of-the drawings and which upon completion of the cutting operation is actuatedby the nger -39 against the action of a spring 40 Yto displace the blank from the plane of travel of the web 4.

In. the present instance I mount theiinger 39A rigidly upon a shaft41 which is rocked by the cam roller. 42 acting through the rocker arm 43 against the spring 44, the saidcam roller 42 contacting with'the peripheral face of the'cam' disk 45 rigidly mounted and 'rotatable with the of carrying Ythe blank cut provide a pair of arcuately shaped fingers 46,

46 mounted upon a rod 47, and arranged to conform approximately to the surface contour of the web carrier roll 5, the said rod 47 being supported and movable about the shaft 8 by means of the rotatable .collars 48 having the arms 49 rigidly supporting the said rod 47. Rotatably mounted upon the rod 47 and connected to the fingers 46 by means of a.' sleeve is a downwardly extending arcuate arm 50 passing' about the lower surface of the roll 5, and heldin spaced relation therefrom by means of aspring 51 secured intermediate the said arm' 50 and a depending-arm 52 rigidly secured upon the aforementioned'rod 47.

With the arm 50 held in spaced relation from` the roll 5 by the said spring 51, the extremities of the lingers .46 grip the blank cut from the web 4 against the said roll 5 and the rotation of the roll 5 in conjunction with the clockwise movement of the rod 47 and fingers 46 about the shaft 8 carries the-blank away from said web to a point below the' said roll 5.vr The rod A4'? supporting the fingers 46 is moved clockwise of the roll 5 by means of the cam roller 52 riding J on the surface contour of the cam disk 53 and operating through the link' train 54 connected 'to said 'rod 47 against the spring 54a. When the ngers 4 5 have' moved the portion cut from the web 4 a predetermined distance clockwise about the roll V5, the blank is released from the grip of the fingers 46 by rocking-the arm f 50, rigidly connected to said fingers; about the rod 47.l Thearm 56 and ngers 46 are rocked about the rod 47 by' means of a cam roller 55 normally engaging the under surface Vof the arm 50, lifting of the said cam roller `being ac- 'feeding thereof.

complished through the levers 56 connected at oneend thereto and at the other 'end to'a second cam roller 57 riding on the peripheral surface of the cam disk 58 land acting against a spring 58a.

In the present instance the cutting of the blank of material from .the web 4 and the dis.-

placing thereof y from the plane of travel of said web by the plunger 38 are so timed in conunction with the cam disks 53 and 58 that the gripping of the blank vby the fingers 46 takes place simultaneously with the depressing of said blank below the web 4, thecarrying of the cut out portion about the roll 5 and the subsequent releasingthereof by tripping the fingers 46 taking place successively after said fingers have gripped the: blank. With the release of the material cut from the web 4 by the tripping of the fingers 46 through the rocking of the arm 50, the material is4 carried by a chute 59 outwardly-of the machine.

A plurality of idler rollers 60 are rotatably mounted upon a rod 61 and abet the movement of the blank out from the web 4 about the roll 5, the pressure of the rollers 60 against the roll 5being eifected by means of a spring 62 acting through the rocker arm 63 which is pivoted about a vrod 64 disposed transversely of the machine.

Adhesive material is deposited on the web 4 105 adjacent the edges of the opening 37 formed therein as described above, during they travel of the said opening 37 over the carrier roll 6. In the present instance I accomplish the depositing of said adhesive substances on the web by rigidly mounting a roller 65 on the shaft 66 arranged vfor rotation by' means of agear. 67 mounted at one extremity thereof and meshed with Athe aforementioned gearY 21. The roll -65 is equipped with a removable segment 68, having a raised welt 69 thereon arranged for contact with the webv 4 adjacent the edges of the aperture 37 therein. The adhesive material is placed upon the raised welt 69 of the segment 68. by previous contact with a roller 70 having a coating of adhesive thereon byreason of the contact of' said roller Y70 with the roller 71 which supports 1 and 2 by means of a toothed gear 135 l and 'rack 76 formed on one under face of the supports 7 4.

- A cellophane or other transparent web 77 is fed from a spool 78 about a roller 79 rotatably mounted upon a shaft 80 and subsequently 140 passes over a. rotatable roller 81 supported on the pivotally mounted .arm 82, provided at its outer extremity with a.spring 83, affording a means of tensioning the said web during the a roller 84, rigidly mounted upon the rotatableshaft 85 and about a similar roller 86 similarly mounted upon a shaft 87. At. this point the tension of the web 77 is maintained by a roller The web 77 is then fed below 145 '88, rotatably mountedupon a spindle. 89 sup- 150 wardly intermediate a roller 95 mounted on the shaft 96 and a roller 97 having diametrically opposed blade or cutter elements 98 disposed obliquely in the peripheral surface thereof with respect to the longitudinal axis of the said roller. The cutter elements 98 on the roller 97 operate to cut predetermined lengths of material from the transparent web 77 against the roller 95 over which the web 77 passes.

The roller 95 and'shaft 96 are rotated by a chain 99 which passes from a wheel 100 on the main shaft 17 of the machine about the Wheel 101 mounted at one extremity of the shaft 98, the said chain in a similarmanner passing about the wheels 102 and 103 respectively mounted upon the shafts 104 and 105. A gear 103a is mounted at the end of the shaft 105 adjacent the support 2 and arranged for rotation therewith, the said gear 1038' meshing with gear 14 mounted on the shaft 10. I'he arrangement described above tends to act as a' balancer or connection intermediate the mechanism driven by the chain 15 and that driven by the chain 99 to more eiliciently time the operation of the machine.

'Ihe severed section of transparent material is projected downwardly of the machine to a platen 106, and is maintained in flat relation thereon by the spaced rods 107. The section of the transparent material is then positioned upon the web 4 which is .held in contact with-the roller 7 by the idler rollers 108 rotatably mounted upon the shaft 109 supported intermediate the rocker armsA 110, 110 pivotally mounted on a rod 111, the said arms 110,'110 secured at their opposite ends to a transverse support 112a on the machine by a spring member 112, the said spring acting through the rocker arms 110 to effect a contact of suicient pressure of the idler.

rollers 108 on the web 4 carried by the roller 7. The length of the material which is severed from the continuous web 77 and placed in overlying relation with the opening 37 in the web 4 is adhered thereto by the adhesive material deposited adjacent the edges of the opening by the segmental rectangular section 69, sucient pressure being applied to the severed section of the web 77 overlying the openings 37 in the web .4 by,

the roller 113 to press the said transparent section into contact with the web 4 during passage, beneath the roller -113 whichis rotatably mounted on a shaft 114 supported in one arm o'f the rocker arm 115. 'I'he other branch of thearms 115 is connected by means of a rod 116 to a lever 117 pivotally mounted about the rod 118 having a cam roller 119 rotatably mounted thereon and arranged for rolling contact with the peripheral contour of a cam disk120 rigidly mounted upon the main shaft 17 of the machine, the said lever 117, in the present instance, being actuated against the action of a spring 121 secured intermediate-the outer extremity of said lever 117 and a rod 122 projecting inwardly of the side wall 2 of the machine.

It should be noted that the roller 113 pressing against the transparent section disposed over the opening 37 in the web `4 is formed in a plurality of sections, spaced longitudinally for the purposeof permitting the contact of the said roller with the transparent material about the rods 107 which overlie the platen 106 for the purpose of maintaining. the transparent section in place thereon.

In..the present instance to eect the accuratel cutting of the webs 4 and 77 respectively, I provide the shafts 32 and 23, having the cutting tools mounted thereon, with novel means for `regulation of the contact pressure of the said the web 4 through the machine and the feeding of the transparent web 77 are suitably timed in conjunction with the operations performed during travel of said webs as to produce finished product which is a substantial improvement over products of similar character produced heretofore, the feed rolls for said web 77 being driven by. suitable gear trains connected in any suitable manner to the main drive system of the machine.
